I did the cleared the entire folder as shown below and still get the same problem...it is terminating when I create a new file and tried to save it
a preferences dialog box
Do one of the following:
(Windows) Choose Edit > Preferences > [preference set name].
(Mac OS) Choose Illustrator > Preferences > [preference set name].
With nothing selected, click the Preferences button on the Control panel.
To switch to a different preference set, do one of the following:
Select an option from the menu at the upper-left of the Preferences dialog box.
Click Next to display the next options, or click Prev to display the previous options.
Reset all preferences to default settings
Resetting preferences can be helpful if you are having problems with the application.
Do one of the following:
Press and hold Alt+Control+Shift (Windows) or Option+Command+Shift (Mac OS) as you start Illustrator. Your current settings are deleted.
Remove or rename the AIPrefs file (Windows) or Adobe Illustrator Prefs file (Mac OS). New preferences files are created the next time you start Illustrator.
Note:  It is safe to remove the entire Adobe Illustrator CS4 Settings folder. This folder contains various preferences that can be regenerated.
